UNITED STATES ALBERT J. LARK, OF HAGERSTOWN, MARYLAND.

CUBLING IRON.

Application filed' July 3,

To allwiwmit may'concem:

Be it known that I, ALBERT J. LARM, a

citizen of Germany, residing at Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Curling Irons, of which the following is a specification. 1

This invention relates to improvements in curling irons and has for an important obj ect thereof the provision ofa device of this character retaining its heat for a greater length'of time than the ordinary construe tion of curling iron, and which at the same time is of such construction that burning of the hair during the curling operation is avoided.

A further object.of the invention is to provide a curling iron having the usual coacting members for grasping the hair between, one of which is grooved and the other of which is in the form of a body adapted to fit into the groove in which this body is formed in two separable sections, one of which is hollow and contains a metal retaining heat for a considerable period of time.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure'l is a perspective view of a curling iron constructed in accordance with my mvention;

Figure 2 is a vertical sectional view through one section of the iron;

Figure 3 is a perspective of the heat retaining rod removed.

Referring now more particularly to the drawings, the numerals 10 and 11 indicate a pair of plier connected members pivoted 'to one another, as at 12. These plier members each embody a body portion and a handle portion, the body portion of the member 11 being formed in two sections 13 and 14:. The section 13 is integral with the handle portion of the member 11 and" is provided with a reduced threaded extension 15.

The section 14 is in the form of a tube range of change and modification without having its outer end closed and its inner end interiorly screw-threaded for coaction with the threaded extension 15 of the section 13. The Walls of the tube 14 are provided with radial perforations 16, and removabl located within the bore of the tube is re 17 of greater thermo capacity than 1924. Serial No. 724,051.

the material from which the tube 14 is formed, that is to say, this rod has the uality of retaining heat for a greater lengt of time than the material from which the tube is formed, as, for example, the tube may be formed from steel and the rod formed from copper or bronze. The coacting section of the other plier member 10 is of ,the usual construction, having a groove 18 for the reception of the tube as is usual.

In the use of the device, the plier members are heated in the usual manner and-the outer shell of the tube 14, being relatively thin, cools rapidly and accordingly is extremely unlikely to be suflicient y hot to scorch the hair at an time during the curling operation. During the curling operation the rod 17 gives oflt" its heat which passes through the openings 16 of the tube to the hair, drying the same to set the curl in the usual manner. If it is desired that the handles of the plier members be formed integrally with the operating or jaw ends thereof, these handle members are preferably provided adjacent the pivot thereof with a plurality of centrally disposed, longitudinally spaced openings .19 through which air can circulate to prevent the passage of heat from the jaw ends to the handle ends.

Among the advantages of my device may be mentioned the fact that, as is well known, in heating curling irons for waving hair, the ooved members becomes very much hotter than the other body member because it of necessity is, of smaller metallic content and burning of the hair is usually caused by the grooved member being so hot.

With my device, however, the heat is retained in the' body member in such manner that it comes in contact with the hair only b v radiation and inview of the fact that the heat is retained in the body memher by employing greater thermo capacity than the grooved member, the latter is not heated to such an extent that there is liability to burn the hair in the practical use of the device.

Since the device is capable of a certain materially departing from the spirit of m invention, I do not limit no self to sue specific structure as hereinbe ore set forth except as hereinafter claed.

L In a curling iron, a pair at plier con nected members having handle ends and op-' erating ends, the operating end of one of said members having a groove receiving the other of the members, the other operating from upon separation of the sections.

2. In a curling iron, a pair of plier connected members having handle ends and operating ends, the operating end ofone of said members having a groove receiving the other of the members, the otheroperating end bein formed in two separable sections, one of w ich is provided with a l gitudinally extending bore and has form (1 in its side wall radially directed openings, a bar of heat retaining material freely mounted within said section and removable therefrom upon separation of the sections, the handle sections of said members being provided adj acent the pivots thereof with a plurality of centrally disposed openings preventing the transmission of heat from the operating ends to the handle ends.

In testimony whereof I afliiz my si ature.
